Giving Makes You Happier than Keeping
Research has shown that giving money to a charity or to help someone else made people happier, and that happier people gave more money to help others, suggesting there is a virtuous circle of giving and becoming happier, which leads to more giving. The research included giving people $5 or $20 and then assigning them a task of giving it away or spending it on themselves. Those people who gave the money to someone else were happier than were the people who spent it on themselves.
Look for opportunities to give and you will be happier.
